Rafa Nadal made a dazzling start to his Wimbledon title defence with an easy win over American Michael Russell on Monday before home favourite Andy Murray produced some indoor fireworks to join the Spaniard in the second round.
World number one Nadal, playing at the grasscourt slam for the first time as defending champion after injury denied him the honour in 2009, beat Russell 6-4 6-2 6-2 after taking a few games to get to grips with the 33-year-old journeyman.
After heavy rain shut down play on the 17 courts not equipped with a roof, Murray made full use of Centre Court's translucent sliding canopy to give British fans some cheer despite a scare against Spain's Daniel Gimeno-Traver.
World number four Murray, who beat Stanislas Wawrinka in the only other whole Wimbledon match to be played under the $130m roof in 2009, reeled off the last 15 games to win 4-6 6-3 6-0 6-0.
Before the rain clouds rolled over south west London five-times women's champion Venus Williams powered past Uzbekistan's Akgul Amanmuradova 6-3 6-1 wearing her latest line in tennis fashion, a baggy ensemble with a large upside down V-shaped opening slashed in the back.
The 31-year-old, who returned from a five-month injury lay-off at Eastbourne last week, struck the ball with her customary power to overwhelm the 97th-ranked Amanmuradova who is still looking for her first Wimbledon win after five attempts.
"Especially having not played a lot, I had a little pressure on me to come out and swing as usual," Williams, one of the oldest players in the women's draw, told reporters.
The American will have youth on her side in the second round, though, when she plays Japan's Kimiko Date-Krumm who beat British wildcard Katie O'Brien 6-0 7-5.
At 40 years and eight months, Date-Krumm became the second oldest player to win a singles match at Wimbledon since Martina Navratilova survived a round in 2004 aged 47.
Vera Zvonareva, the highest-ranked woman playing on opening day, survived a big scare when the second-seeded Russian beat American Alison Riske 6-0 3-6 6-3 and last year's French Open champion Francesca Schiavone also needed a decider to see off Jelena Dokic in a match completed under the roof.
